#PHP Validator

PHP Validator is a lightweight library for validating scalar values, dates, arrays, and nested input structures. Rules are chainable, failures throw a ValidatorException, and successful transformations are returned by get().

#Start here

• Getting started - install the package, validate a value, and handle failures.

#Guides

• Arrays and shapes - validate lists, associative input, and nested structures.
• Optional values - skip rules conditionally and provide defaults.
• Transforms and custom rules - normalize input and add application-specific validation.

#Reference

• API reference - signatures and behavior for every public validation method.

#Project documentation

• Architecture - data flow, repository structure, and implementation constraints.
• Contributing - local setup, change guidelines, and validation steps.

#Common use cases

• Validate form or API input before using it.
• Normalize strings while validating their format.
• Validate every entry in a list.
• Project an associative array onto a known schema.
• Turn identifiers into domain objects after validating them.
• Attach a field name or other context to validation failures.

#Installation

composer require einlinuus/php-validator

The public classes currently use this namespace:

use EinLinuus\PhpValidator\EinLinuus\PhpValidator\Validator;
use EinLinuus\PhpValidator\EinLinuus\PhpValidator\ValidatorException;
